Effective work functions for ionic and electronic emissions from mono- and polycrystalline surfaces
TL;DR: In this article, the effective work functions (ϕ+, ϕe and ϕ−) for positive ion, electronic, and negative-ionic emissions from mono- and polycrystalline surfaces are surveyed comprehensively and also investigated critically for the main purposes of evaluating the most probable values of ϕ+ ϕ e andϕ− for a variety of surface species.

Calculation of the surface binding energy for ion sputtered particles
TL;DR: In this paper, a simple model based on the electronegativity concept is proposed to calculate the surface binding energy of any particles, sputtered from a solid surface by ion bombardment, which is strongly desirable in the case of the ion sputtering of any strong electrone gative (C, N, O, F, Cl, etc.) or electropositive elements (alkali metals, rare earth elements) from semiconductor surfaces, when the strong ionic binding between these elements and the surface atoms can be estimated.
